Is there a max. TB size limit with Windows 7 64 bit machine?

Hello,

I have a DELL Studio XPS Desktop 8100 running with Windows 7 Pro 64 bit.

Is there any limitation as to the max size exrternal drive (TB 2, TB 3 or greater)
that will works with Windows 7?

Is there a max size that will work with e-sata?

Thanks

Stu

Hi stuart253. Up to 3TB you will not have problems with 64bit versions of Windows 7 and Vista.

Thanks for the weblink. I am even more glad that I've stepped over to a x64 OS.

I have several external hdd's, my largest being a WD 2TB. Defragmenting it is a bit problematic for the O&O Defrag 14 Pro that I am using. It takes forever to defragment that hdd; that being the case I do not think to purchase another third party defragmentation software. Instead I will use the software incorporated within Windows 7 and later Win8.

On the whole the Windows 7 defrag appears to get the thumbs up by forum members (my observation).

In cases like this I would simply say "you're welcome" ... but as it came from a lady, I will say, "totally at your disposal, mademoiselle!"

Hi,

Thanks to all who replied. Have purchase a LaCie d2 Quadra 3 TB external hard drive. Connected it to my machine via e-sata. It shows that it is only 746 GB.

My other drives are western digital and are 1 TB and 2TB, these show their proper
capacity, whereas my Lacie 3 TB does not.

While I am waiting for LaCie to respond, anyone have any ideas?

Thanks

Stu

If your Lacie 3TB is formatted with GPT then Windows should see the 3TB.
See post #3. Of course 3TB is base 10 and TiB (base 2) will record less.

And... just type "compmgmt.msc / s" without quotes in the search bar at the "start" and hit enter. On the left half of the window that opens, click "Disk Management". There, click the right mouse button on the hard drive in question and click "convert to GPT disk" as shown below. Let us know the results.
